Peripheral and Interface Components
Parameters
Table 5-8 lists the configuration parameters of the TZSwitch component.
Table 5-8 TZSwitch configuration parameters
Parameter
name
Description
Type
Allowed
value
Default
value
secure
normal
Default routing for
secure transactions.
Default routing for
normal transactions.
Integer 0, 1, 2, 3 1
Integer 0, 1, 2, 3 2
Note
The secure and normal parameter values control the initial state of the TZSwitch component.
Possible values for these parameters are:
0 ignore these transactions
1 forward the transactions to pvbus_port_a
2 forward the transactions to pvbus_port_b
3 generate an abort for these transactions.
The numbers used for initial configuration are not the same as the enumeration constants used
to control routing at runtime.
Registers
The TZSwitch component has no registers.
Debug features
The TZSwitch component has no debug features.
Verification and testing
The TZSwitch component has been tested as part of the VE example system using VE test suites
and by booting operating systems.
Performance
The TZSwitch component is optimized to have negligible impact on transaction performance.
Note
When memory remap settings are changed when there might be a significant effect on
performance.
Library dependencies
The TZSwitch component has no dependencies on external libraries.
